18 LASIN Kinetic Energy Plasma oscillation longitudinally Along magnetic field Due to the higher magnetic field in propagation direction Redistribution of longitudinal momentum To the transverse direction
19 Potential t=2.25ps t=0s t=1ps t=1.5ps
20 LASIN -Energy Ratio variation of total energy/energy (~ 3ps) -Less comparing with previous case 6% -Due to the variation of magnetic field? -Using different type of integrators -Longer simulation needed -Cyclotron frequency ->characteristic time τ c =6e-12s -Plasma frequency -> characteristic time τ= 3.5e-13s -Debye length λ D =0.2µm New strategy -> finer mesh dual mesh
21 Conclusion & Outlook Dynamic in strong magnetic field (Solenoids, Toroids& Fringing fields+ magnetic coupling) Collective phenomena (Gabor Lens, electrons&ions) Correction coils Space-charge effects & Aberrations Experience -> Development of efficient simulation and design tools for future Linacs
